Abstract
Using membrane processes compared with conventional treatments provides numerous advantages including production of a constant water quality, addition of fewer chemical reagents, lower energy requirements for maintenance, compactness and quick start‐up. In this study are described pilot experiments which were conducted in the Research Centre of Compagnie Générale des Eaux at Maisons Laflitte. Two types of membranes were tested to compare their performances in different applications of water treatment: organic hollow fiber membranes (ultrafiltration) and ceramic multichannel membranes (ultra‐ and micro filtration). Treatment of karstic waters with this process is actually a good alternative. For surface waters, more work is required to understand the mechanisms of membrane fouling and to reduce operating and investment costs.
